failures during the move.

Both LVM and VxVM enable online
disk storage management. They both
build virtual devices, called volumes,
on physical disks. Volumes are not
limited by the underlying physical
disks, and can include other virtual
objects such as mirrors. Volumes are
accessed through the HP-UX file
system, a database, or other
applications in the same manner as
physical disks would be accessed.
